Attaches or replaces non-manifold vertex mapping data to the provided mesh.
Note: Failure occurs if the DynamicMesh does not have attributes enabled or if the provided array is not long enough to provide a mapping value for each DynamicMesh vertex id.
false on failure (no attribute will be attached to the DynamicMesh in this case)
